Travel safety device for motor vehicle
First Claim
1. A travel safety device for a vehicle comprising:
- an object detecting unit which detects an object existing in a traveling direction of the vehicle;
a correlation calculating unit which calculates a correlation involving a distance between the vehicle and the object on the basis of a detection result of the object detecting unit;
a safety unit including an automatic brake unit which automatically decelerates the vehicle and a seatbelt device which automatically tightens the seatbelt and releases the tightening thereof; and
a safety device operation control unit which determines a possibility of a contact between the vehicle and the object on the basis of the correlation calculated by the correlation calculating unit and for controlling operation of the safety device when it is predicted that there is a possibility of a contact wherein the safety device operation control unit simultaneously actuates the automatic brake unit and seatbelt device when it is predicted that there is a possibility of a contact.

Abstract
A travel safety device for a vehicle comprises: an object detecting unit (114) for detecting an object existing in the traveling direction of the vehicle (100); a correlation calculating unit (39) for calculating a correlation involving the distance between the vehicle (100) and the object on the basis of a detection result of the corresponding object detecting unit (114); an automatic brake unit (120) for automatically decelerating the vehicle (100); a safety device (122) including a seatbelt device (15) for automatically tightening the seatbelt (14) and releasing the tightening thereof; and safety device operation control units (38, 39, 43) for determining a possibility of a contact between the vehicle (100) and the object on the basis of the correlation calculated by the correlation calculating unit (39) and for controlling the operation of the safety device (122) where it is predicted that there is a possibility of a contact; wherein the safety device operation control units (38, 39, 43) simultaneously actuate the automatic brake unit (120) and seatbelt device (15) where it is predicted that there is a possibility of a contact.

11. A seatbelt device comprising:
-
a seatbelt which restrains an occupant of a vehicle in a seat;
a contact predicting unit which predicts a possibility of a contact between the vehicle and an object;
an electric motor which tightens the seatbelt when a contact is predicted by the contact predicting unit;
a tightening releasing unit which releases the tightening of the seatbelt; and
a control unit which controls the electric motor and the tightening releasing unit;
wherein the control unit carries out a warning operation to issue an alarm to the occupant by means of the seatbelt by controlling the electric motor and the tightening releasing unit so that tightening of the seatbelt and releasing thereof are alternated. - View Dependent Claims (12, 13, 14)
